Great thanks to you v1nce, Lazur URH and hulf2012.
Your are really "formidable" in french
I will not use AI now with Mountain Lion.

Permission are all read and write.

I put my file in copy next, if you want to try open it with your Inkscape.

Thanks.

Are you trying to open the file by clicking?

Yes

Are SVG files associated with Inkscape?

Yes

Do other not edited SVG files open?

Yes

You can see informations in the copy.

I don't understand why it can't open

Hello,

I test Inkscape to replace Illustrator.
My file is in SVG.
XQuartz run.
I open my file with Inkscape and I work correctly.
I save it : OK
But when i want to open this file, i cannot.
There is a window like this (failure of the loading of the file…)

Do you have some ideas ?

Thanks.
